Re: after the FBI searched
If you read The Washington Post article it's experts consider that it is unlikely that much of the content was planted, especially the emails

Emails have the advantage that they can be analysed/verified on the SMTP servers, thereby providing 2 independent.
If you believe that the information was planted there then you also have to understand that whoever planted it actually had access to his emails and therefore all the leverage that they could ever want.. If such was the case then there was no need to plant the emails on a broken laptop, they could have easily distributed them on a multitude of varying platforms.
